About the C-TEK Standard Disc Brake Rotors Line

The C-TEK Standard Disc Brake Rotors line by Centric is designed to meet OEM specifications for standard replacement rotors. This product line focuses on delivering consistent performance with solid rotors that feature a smooth surface type, ensuring proper pad contact and braking efficiency. The 121.35027 rotor is part of this line, providing a direct-fit solution for Mercedes-Benz vehicles requiring reliable braking components without additional features like venting or ABS tone rings.

Detailed Product Description

This Centric disc brake rotor is a solid type rotor, meaning it does not have vented channels but offers a smooth surface for even brake pad wear. The nominal thickness of 0.354 inches (9.000 mm) ensures adequate material for longevity, while the discard thickness of 0.287 inches (7.300 mm) indicates the minimum safe thickness before replacement is necessary. The rotor’s outside diameter of 10.157 inches (258.000 mm) and overall height of 2.177 inches (55.300 mm) are designed to match the braking system specifications of Mercedes-Benz C220, C230, and C280 models. The rotor mounts using five lug holes arranged on a 4.409 inch (112.000 mm) bolt circle diameter, with a center hole diameter of 2.638 inches (67.000 mm) for proper hub fitment. This rotor does not include an ABS tone ring or bearings, so those components must be sourced separately if required.

Common Applications and Problem Solving

• Replacement for worn or warped rotors causing brake pulsation or noise
• Restores proper braking performance on Mercedes-Benz C220, C230, and C280
• Addresses rotor thickness below manufacturer discard limits
• Eliminates uneven pad wear due to rotor surface imperfections
• Suitable for vehicles requiring solid rotors without ABS tone ring integration

Installation Notes and Tips

• Verify rotor thickness before installation to ensure it meets minimum discard thickness
• Clean rotor surface and hub mounting area to prevent runout and vibration
• Use proper torque specifications on lug nuts to avoid rotor warping
• Check compatibility with existing brake pads and hardware
• ABS tone ring and bearings are not included; confirm if replacement is necessary
